用DEPT技术和2D碳氢相关谱对峰峰肥煤几个液体馏分的研究

STUDY ON THREE FRACTIONS OF FENG FENG FAT COAL DERIVED LIQUID BY DEPT TECHNIQUE AND 2DNMR

本文利用多脉冲ＤＥＰＴ技术和二维碳氢相关实验对峰峰肥煤的几个液体馏分进行了分析，获得了较多的结构信息。Ｆ（１１）馏分是由正庚烷冲洗下来的，主要包含不同链长的直链、支链烷烃和环烷烃组分。Ｆ（１２）是由苯溶剂淋洗下来的馏分，以芳香族化合物为主。由四氢呋喃冲洗下来的Ｆ（１４）馏分含有较多的极性化合物，主要有杂环化合物，各种取代的环烷烃等。

Three fractions of Feng Feng fat coal derived liquid were investigated by DEPT technique and 2D C─H correlation spectroscopy. Some structural information were obtained,F1l fraction was separated out by n-heptane solvent, which mainly included straight and branched alkane with different chain length, and cycloalkanes, Aromatic hydrocarbons were the main constituents of F12, which was eluted using benzene solvent. F14 fraction was separated out using THF, therefore it contained more polar compounds, which consisted of heterocyclic compound and all kinds of substitued cyclic hydrocarbons.
